a population forms a normal distribution with a mean of u=80 and a standard deviation of o=15. for each of the following samples, compute the zscore for the sample mean and determine whether the sample mean is a typical, representative value or an extreme value for a sample of this size.
a. m=84 for n=9 scores
b. m=84 for n=100 scores

Use the same process as indicated in another of your posts.
